Wide Band Oxygen (O2) A/F Sensor Calibration Checker

Now
you can check your wide band O2 sensors and see if they have gone bad or your
engine is really running that lean.

You
screw in your sensor and supply the nitrogen (or argon) gas, and the propane or
shop air at the specified rate to produce most any A/F mixture, from 11:1 to as
lean as 17:1.(These fittings are on
the back side of the device in picture.Gases
not included with calibrator.)

Not
only do you check your sensor, but your entire A/F recording system, including
the electronics, wiring, computer or data logger and software calibration.
